Parameters

Parameter	Description	Value
vpn-target	Adds a VPN target to the VPN. A VPN target can use any of the following formats: 16-bit AS number:32-bit user-defined number For example, 1:3. An AS number ranges from 0 to 65535. A user-defined number ranges from 0 to 4294967295. The AS number and the user-defined number cannot be 0s at the same time. That is, a VPN target cannot be 0:0. 32-bit IP address:16-bit user-defined number For example, 192.168.122.15:1. An IP address ranges from 0.0.0.0 to 255.255.255.255. A user-defined number ranges from 0 to 65535. Integral 4-byte AS number:2-byte user-defined number, for example, 65537:3. An AS number ranges from 65536 to 4294967295. A user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. That is, a VPN target cannot be 0:0. 4-byte AS number in dotted notation:2-byte user-defined number, for example, 0.0:3 or 0.1:0. A 4-byte AS number in dotted notation is in the format of x.y, where x and y are integers that range from 1 to 65535 and from 0 to 65535, respectively. A user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. That is, a VPN target cannot be 0.0:0.	-
import-extcommunity	Receives routing information carrying specified extended community attributes.	-
export-extcommunity	Specifies the extended community attributes carried in routing information to be sent.	-
both	Specifies the extended community attributes of the received and the sent routing information.	-
all	Deletes all the VTs.	-
